The first step to replace power steering pumps for 4.8l, 5.3l, and 6.0l engines requires dealign the power steering pulley then lifting the vehicle. Proceed by removing the bolts securing the oil pan skid plate along with the skid plate when equipped. Position a drain pan underneath your vehicle. The power steering pressure hose needs to be detached from the pump underneath the car before lowering the car. After accessing the power steering return hoses to the pump with clamps (3,5) users should remove those components. Start by removing the lower intermediate shaft from the steering gear and then proceed with removing the bolt which attaches the rear bracket to the engine followed by the front pump bolts. After removal of the pump from the vehicle you need to remove the bracket that secures the pump at its rear. Installation requires attaching the bracket to the pump rear portion followed by tightening all rear bracket retaining nuts to 50 nm (37 ft. Lbs.). Secure the Power Steering Pump by installing a bolt which should be tightened to 50 nm (37 ft. Lbs.) at the engine end of the rear bracket. The bolt tightening process on the pump front should reach 50 nm (37 ft. Lbs.) after which the Power Steering Pump return hoses (2,4) can be installed with retaining clamps. Reposition the vehicle to rise it up and affix the power steering pressure hose to the pump while tightening the fitting to 28 nm (20 ft. Lbs.). Reinstall the oil pan skid plate after which secure the bolts to 20 nm (15 ft. Lbs.) until the vehicle rest on the ground. The technical process ends with reinstalling the intermediate shaft before adding power steering system fluid then performing a bleeding procedure.
